Binder



G. B. WISER Aug. 31, 1954 BINDER Filed June 20 INVENTOR. uy BROWN WISER ATTORNE aiented Aug. 31, 1954 D STATES PATENT OFFICE Claims.

The present invention relates generally to binders, and is more particularly concerned with improvements in temporary binders which may be utilized for the protection of publications such as periodicals, magazines, telephone directories, and the like, in libraries, reading rooms, reception rooms, and other more or less public places, wherein such publications are subjected to considerable handling and wear.

One object of the herein described invention is to provide a binder which is pleasing in appearance, durable, a binder which is easily attached to a publication and securely retained in attached position, and which is economical of manufacture.

A further object of the invention resides in the provision of a temporary binder for a publication, wherein the publication is securely retained within the binder by a novel clamping bar arrangement associated with novel latching means for the clamping bar.

A still further object of the invention is to provide novel means for securing the binder attaching means to the back structure of the binder.

Still another object of the invention is to provide unique securing means for clampingly attaching the binder to a magazine or other publication, wherein the attaching means is secured to the back structure of the binder in such a way as to form spaced paths for cooperation with projections on a clamping bar, so as to more efiiciently secure the binder and publication.

Further objects of the invention will be brought out in the following parts of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations on the scope of the invention defined in the appended claims.

Referring to the drawings, which are for illustrative purposes only:

Fig. 1 is an isometric view showing the binder of the present invention attached to a magazine;

Fig. 2 is a longitudinal section through the back structure and attaching means of the binder;

Fig. 3 is a fragmentary sectional view having cutaway portions, the section being taken substantially on line 33 of Fig. 2;

Fig. 4 is a similar view, the section being taken substantially on line 4-4 of Fig. 2; and

Fig. 5 is an enlarged fragmentary sectional view at one end of the back structure showing details of mounting the attaching means on the back of the binder.

Referring generally to the drawings, for purposes of illustration. the binder of the present invention is disclosed as comprising a pair of cover members it of suitable material, and have been shown as consisting of a clear plastic in order that the title and other indicia of a publication secured in the binder may be readily viewed through the cover members. Identification of the magazine in the binder is thus facilitated, and the necessity of placing identifying indicia on the outside of the binder cover is eliminated. Moreover, the utilization of a plastic provides a very durable binder cover which stands up well under hard and extreme usage.

The cover members are secured at their inner edge margins l [-1 l' to the edge margins l2--I2 of a back strip 13 of suitable material. For such purpose, I have utilized a flexible plastic commonly known as polyvinyl-chloride, so that this back strip not only serves as a back for the binder, but also provides a hinge for the cover members. The utilization of plastic materials as herein described for the back strip l3 and cover members Hi, permit these members to be secured together at their overlapped marginal edges l2 and II by electronic or radio frequency bonding, thereby eliminating the use of bonding materials such as glue which serve to attract rodents and vermin.

As shown in Figs. 2, 3 and 4, the back structure of the binder is reenforced by means of an elongate rigid back bar 14 of channel construction, and having lateral flanges I5 and 6. The back bar I4 is attached to the back strip l3, with its side flanges projecting and between which the back of the magazine may be disposed and retained in attached position by means of a clamping bar H which will subsequently be more fully described.

The back bar It! is secured at intervals to the back strip. For such purpose, the back bar is provided with a plurality of sets of slots, each set comprising a pair of transversely extending parallel spaced slots l8 and I9 as shown in Fig. 5. A securing strip 20 of suitable material, in this case being of the same material as the back strip 13, is threaded through the slots so as to provide a raised pad forming portion 2! lying within the channel between the associated slots, and end marginal portions 22 lying between the back bar and back strip. These end marginal portions 22 are secured to the backstrip [3 by electronic or radio frequency bonding in a manner well understood in the art. In the arrangement described above,.the bonding is facilitated as the back bar l4 provides a built in electrode in engagement with one surface of the material to be bonded. By the foregoing unique arrangement, it is possible to utilize electronic bonding for obtaining an attachment between a plastic back strip and a metallic back bar.

A pair of posts 23 and 24 are respectively mounted at the ends of the back bar [4, each of the posts having a slot opening 25 extending therethrough and respectively opening into the confronting face surfaces of the posts, as clearly shown in Fig. 2. A threaded bore 26 is provided in each post, this bore communicating with the slot 25 and being adapted to mount therein a clamping screw plug 21 for engagement at its imier end with the adjacent edge of the clamping bar, and by means of which the clamping bar may be moved toward the back bar l4 into clamping position and secured against removal.

The post 24, as shown in Fig. 5, is rigidly secured to the associated end of the back bar If by a post mounting stud 28 or other suitable means. This post also serves as a pivotal mounting for the clamping bar H, the associated end of the bar being provided with an elongate slot 29 through which a pivot pin 30 extends. It will be noted that the slot 29 extends in a transverse direction of the clamping bar so as to permit lateral movements of the bar end within the slot 25 by means of the clamping screw plug 2'1. At the same time, however, the pivotal mounting of the clamping bar I! permits swinging movement thereof as shown in dotted lines in 2 about the ivot pin 30 as a fulcrum.

The other post 23 is utilized as a latch for latching and releasing the bar I! for swinging movement to permit attachment of the binder to a publication or magazine. The free end of the clamping bar is adapted to enter the slot 25 of post 23. It will be apparent, by reference to Fig. 2, that the free end of the clamping bar cannot be swung into the associated slot 25, when the post 23 is in the full line position as shown in Fig. 2. The post 23 is therefore hinged for pivotal movement by securing it to the adjacent end of the back bar I4 by means of a suitable pivot pin 3!, the outside bottom edge of the post being shaped as shown at 32 so as to permit movement of the post from full line to dotted line positions, as shown. In the dotted line position, it will be observed that the clamping bar il may be swung toward the back bar it until it is in substantially parallel relation thereto. In order to latch the clamping bar in this position, the post 23 is swung about its pivot from the dotted line position to full line position, this movement causing the associated end of the clamping bar to enter the slot 25 of the post.

It will therefore be apparent that if a magazine or other publication is mounted with its back in the channel i l between the side flanges iii and 6, with the clamping bar I! extending between the rear margins of the magazine pages approximately at the center of the back, that if the post 23 is moved to full line position so as to latch the free end of the bar' against outward swinging movement, actuation of the clamping screw plugs in a direction to move the bar to clamping position will secure the magazine within the binder until it is desired to remove the same.

In order to increase the clamping. effect, and more securely hold the magazine within the binder, the clamping bar I? is provided with a plurality of spaced toothed projections on its lowermost edge as indicated by the numeral 33. The projections 33 are so spaced as to correspond with the spacing between cooperatively associated pads 2|, the projections and pads thus coacting to more securely retain the binder in attached position on the magazine or publication.
